This locus encodes a member of the nicotinic acetylcholine receptor family of proteins. Members of this family of proteins form pentameric complexes comprised of both alpha and beta subunits. This locus encodes an alpha-type subunit, as it contains characteristic adjacent cysteine residues. The encoded protein is a ligand-gated ion channel that likely plays a role in neurotransmission. Polymorphisms in this gene have been associated with an increased risk of smoking initiation and an increased susceptibility to lung cancer. Alternatively spliced transcript variants have been described. [provided by RefSeq, Nov 2009].

The following CHRNA3 gene cDNA ORF clone sequences were retrieved from the NCBI Reference Sequence Database (RefSeq). These sequences represent the protein coding region of the CHRNA3 cDNA ORF which is encoded by the open reading frame (ORF) sequence. ORF sequences can be delivered in our standard vector, pcDNA3.1+/C-(K)DYK or the vector of your choice as an expression/transfection-ready ORF clone. Not the clone you want?

** You may select a custom vector to replace pcDNA3.1+/C-(K)DYK after clone is added to cart.

** GenScript guarantees 100% sequence accuracy of all synthetic DNA constructs we deliver, but we do not guarantee protein expression in your experimental system. Protein expression is influenced by many factors that may vary between experiments or laboratories. In addition, please pay attention to the signal peptide, propeptide and transit peptide in target ORF, which may affect the choice of vector (N/C terminal tag vector).

***One clone ID might be correlated to multiple accession numbers, which share the same CDS sequence.

Comment: REVIEWED REFSEQ: This record has been curated by NCBI staff. The reference sequence was derived from BC006114.1. This sequence is a reference standard in the RefSeqGene project.
Transcript Variant: This variant (2) differs in the 3' coding region and 3' UTR, compared to variant 1. The resulting isoform (2) has a distinct C-terminus and is shorter than isoform 1.
Publication Note: This RefSeq record includes a subset of the publications that are available for this gene. Please see the Gene record to access additional publications.
